ABSTRACT:
FIELD OF THE INVENTION
The present invention pertains to a flush-mounted flush tank, with a tank body, which has a bottom wall, side walls with a front wall and a cover wall, as well as an inspection opening.
BACKGROUND OF THE INVENTION
Flush-mounted flush tanks have been known for a long time and are described in, e.g., EP-A-0 544 616 and DE-A-31 39 834. Both the manufacture and the mounting of such flush-mounted flush tanks are comparatively complicated.
SUMMARY AND OBJECTS OF THE INVENTION
The basic object of the present invention is to provide a flush-mounted flush tank of the type mentioned that can be manufactured and mounted in a simpler manner and less expensively and is nevertheless reliable in operation.
This object is accomplished in a flush-mounted flush tank of this type by the front wall and the cover wall each having an inspection opening, which can be arranged optionally for actuation from the top or for actuation from the front. The flush-mounted flush tank according to the present invention has the essential advantage that only a single tank body needs to be manufactured for the two usual types of actuation. It is no longer necessary to manufacture two different flush tanks for actuation from the top and for actuation from the front. Thus, a single production line is sufficient for the manufacture of the two types of flush-mounted flush tanks. Since only one tank body is used, mounting is also more uniform and consequently simpler. As a consequence of the more universal use of the flush-mounted flush tank, stock keeping is also simplified. The flush-mounted flush tank according to the present invention may be pre-fitted already in the factory for actuation from the top or from the bottom. The upper inspection opening is closed in one case and the front inspection opening in the other case. The mounting will be especially simplified if a building protection frame is fastened to the tank body already in the factory according to a variant of the present invention. However, the flush-mounted flush tank according to the present invention can also be used such that one inspection opening or the other is attached only at the site of the installation corresponding to the intended actuation. Consequently, shipping of the wrong type of flush tank cannot happen.
Mounting is further simplified if the two inspection openings are designed as congruent openings. The means for the installation and the mounting of the actuating means is now the same for both types of actuation. For example, the same building protection frame may be used for actuation from the front and for actuation from the top.
The number of necessary parts can be further reduced if, according to a variant of the present invention, the building protection frame has at least one detachable cover, which can also be used to close the inspection opening not needed at the same time. The cover can thus be used as a closing plate. The building protection frame preferably has two such detachable covers. One of these two covers is used at the time of mounting as a closing plate to close one of the inspection openings. The other cover remains on the building protection frame until after building the wall and thus it prevents foreign bodies from penetrating into the flush tank during the building of the wall. Thus, not only does the flush-mounted flush tank according to the present invention substantially facilitate the manufacture and the mounting, but it also makes it possible to substantially reduce the number of different individual parts and consequently to simplify stock keeping.
According to a variant of the present invention, the actuating means is designed such that it can be used for both actuation from the front and actuation from the top. Thus, the same actuating means can be used for both types of actuation. A lever is preferably mounted for this purpose on a bearing block, wherein an axis of rotation of the lever is located on the bisectrix of the angle between the front and upper edges. According to a preferred embodiment of the lever, the latter has two fastening points in an angular arrangement. One of these fastening points is used for a horizontally directed push bar for actuation from the front, and the other fastening point for the vertically directed push bar for actuation from the top. The actuation can thus be performed with a prior-art cover plate. If a building protection frame and a closing plate form one unit according to a variant of the present invention, mounting can be further simplified and the number of individual parts can be further reduced. The building protection frame and the closing plate are arranged such that the building protection frame is placed on one inspection opening and the other inspection opening is closed with the closing plate at the same time. Provisions are preferably also made in this case for the same unit to be able to be used for both types of actuation.
The various features of novelty which characterize the invention are pointed out with particularity in the claims annexed to and forming a part of this disclosure. For a better understanding of the invention, its operating advantages and specific objects attained by its uses, reference is made to the accompanying drawings and descriptive matter in which preferred embodiments of the invention are illustrated.
